Plug and Play connection cable kit for various BMW models of the late E-series / F-series and G-series. Is required to connect a retrofit amplifier with equipment variant "BMW HiFi" / "SA676". The custom-fit connector picks up the audio signal before the amplifier and allows thanks to the built-in Hi-Lo level converter, the connection of a RCA cable. The new retrofit amplifier can now be connected to this. Already pre-stripped cable ends and twisted, high-quality, fine-stranded copper cables feed the audio signal back to the original wiring harness. Perfectly cut to length for installation of the retrofit amplifier in the rear of the vehicle. Front & rear signal are tapped.
